Abstract:
Objective:To investigate the possible role of tag single nucleotide polymorphisms in cAMP signaling pathway in patients with recurrent major depressive disorder in Chinese Han population.
Methods:1 030 patients with recurrent major depressive disorder according to the DSM-Ⅳ criteria were recruited as case group and 851 age- and gender- matched healthy volunteers were recruited as control group.The sequenom mass spectrometry method was adopted to explore the genotype and allele frequency distributions of tag single nucleotide polymorphisms of cAMP signaling pathway in the two groups.
Results:The differences of genotype and allele frequencies of the ADCY7 gene loci rs1064448 and HTR2A gene loci rs17068986 were significant between case group and control group(P<0.05). The difference of the genotype frequencies(492∶423∶112, 356∶401∶91; 538∶392∶94, 414∶371∶61; 24∶165∶838, 3∶150∶694; 219∶468∶337, 139∶418∶237; 153∶481∶393, 115∶446∶286; 53∶286∶688, 25∶296∶524)of the ADCY9 gene loci rs2531995, BDNF gene loci rs10835210, rs7124442, CREB1 gene loci 4675690, rs2551645 and the HTR2A gene loci rs3125 were significant in case-control group(P<0.05); while the rest tagSNPs had no statistical difference in genotype and allele distribution frequencies in case-control group(P>0.05). In gender-specific analyses, the differences of the genotype and allele frequencies of the ADCY7 gene loci rs106448 and CREB1 gene loci rs2551645 were significant in male case-control group(P<0.05); the differences of the genotype(195∶177∶49, 193∶423∶41; 221∶158∶42, 237∶201∶28; 83∶188∶148, 85∶237∶122; 24∶113∶284, 10∶176∶281)of the ADCY9 gene loci rs2531995, BDNF gene loci rs10835210, CREB1 gene loci rs4675690, and HTR2A gene loci rs3125 were significant in male case-control group(P<0.05); while the rest tagSNPs had no statistical difference in genotype and allele distribution frequencies in male case-control group(P>0.05). The differences of the genotype and allele frequencies of the ADCY7 gene loci rs1064448 and HTR2A gene loci rs17068986 were significant in female case-control group(P<0.05). The differences of the genotype(16∶94∶497, 1∶73∶308; 136∶280∶189, 54∶181∶115)of the BDNF gene loci rs7124442 and CREB1 gene loci rs4675690 were significant in female case-control group(P<0.05). The differences of the allele frequencies(840: 372, 493: 267) of the ADCY9 gene loci rs2531995 were significant in female case-control group(P<0.05), while the rest tagSNPs had no statistical difference in genotype and allele distribution frequencies in female case-control group(P>0.05).
Conclusion:The ADCY7 gene loci rs1064448 and CREB1 gene loci rs4675690 are associated with recurrent major depressive disorder in Chinese Han population.
